Hi, While I noticed an automatic core binding in Open MPI 1.8 (which in a shared cluster may lead to oversubscribing of cores), I can't spot this any longer in the 2.x series. So the question arises:
- Was this a general decision to no longer enable automatic core binding? First I thought it might be because of: - We define plm_rsh_agent=foo in $OMPI_ROOT/etc/openmpi-mca-params.conf - We compiled with --with-sge But also started on the command line by `ssh` to the nodes, there seems no automatic core binding to take place any longer. -- Reuti _______________________________________________ users mailing list users@lists.open-mpi.org https://rfd.newmexicoconsortium.org/mailman/listinfo/users
